The Dell XPS 13 is great. It runs Linux very well. The WiFi is excellent. It's got an aluminum chassis. The part where your hands rest is carbon-fiber composite so it isn't cold in the morning. The HiDPI touch screen is incredible, and the performance is pretty amazing. There is a single hinge stretching across most of the laptop for the screen (like the Macbook), unlike the flimsy set of two hinges on most laptops. Most laptops I've seen have broken at the hinge. I customized mine by maxing out the processor, screen, 16 GB RAM, and 512 GB SSD. The unboxing experience was very well-designed and it really felt premium.
In short, this is the good non-Apple laptop that you're looking for.
